Delays were reported on the MBTA's Red Line for the second day in a row.
According to the agency, the delays were due to a disabled train at JFK/UMass as well as a signal problem.
Riders were unhappy with the delays and took to social media to share their frustrations.
@Patriot_Reign tweeted "@MBTA Been on redline last 25 minutes-zero announcements #mbta"
"Stuck on the #RedLine it's way too hot for this...#MBTA" tweeted Kris Kream.
Shortly after 7 p.m., the MBTA tweeted that regular service on the Red Line had resumed.
On Monday afternoon, there were severe delays reported on the Red Line due to a power problem at the Broadway station.
The Green Line also experienced delays Monday morning due to a signal issue.
